Abstract

Improvements in devices for concentrating solutions, especially a solution of a solution in a solvent, by bringing into contact in a room of said solution with a stream of hot gas circulating in a space provided above the solution, said hot gas being suitable for evaporating and entraining said solvent, characterized in that said devices comprise means for creating in said space a network of splashes of solution that entangle each other in order to make intimate and violent contact between said solution and said hot gas, means being provided to subordinate spatially the flow rate as well as the temperature of said gas to the final degree of concentration of said solution.
